Your child's developmental milestones from 1 to 2 years

Your child’s first 5 years will see huge changes in their development. As they grow, their skills develop.

These include:

  • gross motor skills – using large muscles that coordinate body movements such as standing, sitting upright and walking
  • fine motor skills – using small muscles for accurate coordinated movements such as holding a toy and drawing with a crayon
  • communication and hearing
  • social and emotional
  • problem-solving, learning and understanding

The ages given for milestones in this guide are an average. Every child is different. Most children should be meeting these milestones.

Helping your child manage their feelings

Information:

Talk to your GP or public health nurse (PHN) if you are concerned about your child’s development. They may carry out more tests or refer your child to a specialist

By 14 months

By this age most babies will achieve these milestones:

Gross motor

Your toddler will start to walk independently.

Fine motor

They’ll be able to build towers using 2 cubes.

Communication and hearing

Your toddler will be able to say one word at a time, such as “no” or the name of a particular object.

Social and emotional

They’ll play alongside other children but not with them. This is called parallel play.

Your child may:

  • be easily frightened by loud noises - they may cry if they are startled by a sound like a door slamming
  • want your attention and praise
  • react to changes in their daily routine
  • be able to soothe and comfort themselves as well as getting comfort from you

Problem-solving, learning and understanding

Your toddler will put 2 cubes into 1 hand to help them take a third cube.

By 16 months

By this age most babies will achieve these milestones:

Gross motor

Your toddler will crawl upstairs. Their legs will be stiff when they run.

Fine motor

They’ll be able to build towers using 3 cubes.

Communication and hearing

Your toddler will have a vocabulary of 5 to 10 words.

Social and emotional

They’ll start doing pretend play. This is when your toddler pretends objects or actions are other make-believe objects or ideas as play. For example, pretending blocks are a house or pretending to talk on a phone.

Your child may:

  • enjoy getting praise and attention from you
  • get upset when they don’t get something they want
  • not want to share toys with other children

Problem-solving, learning and understanding

Your toddler will find toys hidden under layers.

By 20 months

By this age most babies will achieve these milestones:

Gross motor

Your toddler will walk upstairs while holding your hand.

Fine motor

Your child will be able to:

  • stack 3 to 6 small blocks on top of each other
  • turn the pages of a book by themselves

Communication and hearing

Your toddler will be able to point to 6 body parts.

Social and emotional

They’ll be able to feed themselves and take off clothes.

Problem-solving, learning and understanding

Your toddler will scribble back and forth using a crayon.

By 24 months

By this age most babies will achieve these milestones:

Gross motor

Your toddler will be able to:

  • jump into place
  • kick a ball
  • throw a ball

Fine motor

They’ll be able to make a ‘train’ using cubes. They’ll be able to use a crayon or marker to copy a vertical line after seeing you do it first.

Communication and hearing

Your toddler will be able to say 2 or 3 word sentences. They will refer to themselves by their names. They will have 50 or more words in their vocabulary.

Social and emotional

Your toddler will:

  • match objects to pictures
  • imitate or copy others to please them
  • not necessarily be distressed if separated from you and will continue with their activity

Your child may:

  • test limits to see if they can get their own way
  • have temper tantrums when they don’t get their way
  • be less frightened by things like heights or strangers
  • become less upset by short separations from you
  • become more difficult to put to bed
  • cry if you’re cross or upset with them
  • be jealous if you give attention to other young children
  • have an understanding of self - for example, recognising their face in a mirror

You may notice your child:

  • asking lots of questions
  • being interested in different parts of their body - including their genitals
  • saying “no” often - this shows they are gaining confidence
  • enjoying sharing their achievements with you and getting your praise and encouragement
  • being unable to take the feelings of others into account - they think the world revolves around them
  • becoming interested in children of the same age and other adults and talking to them
  • becoming more confident so they are able to be apart from you for short periods of time - for example going to pre-school

Problem-solving, learning and understanding

Your toddler will continue to do pretend play. They will copy a line drawn on a piece of paper.
